Change in Nominal income = 5%

Change in real income = 2.9 %

Explanation:

Real income is the amount of basket of goods and services that can be actually purchased. It is the nominal income adjusted for inflation.

Real income = (CPi in base base year / CPI current year) * Nominal income

Real income for Sabrina

= (100/102) * 105,000

= 102,941.1765

Change in real income = (102,941.1765 - 100,000) / 100,000

= 2.9 %

Change in Nominal income = (105,000-100,000) / 100,000

= 5%
